I have read it on this board with depressing regularity:
"We need a novel about Dooku!" "We need a novel about Darth Cognus!", "We need a novel about every Sith Lord from Darth Bane to Darth Plagueus!" "We need a picture of Cal Omas!"

I'm tired of material focusing on the deeds of force-users may they be Sith, Jedi or Je'Dai. We need something from the POV of a non-force-user and I think a novel about Wilhuff Tarkin could be a great read.

Think about it. If Darth Plagueus, who was only mentioned in two sentences in ROTS can be made into a bestseller, than why not a novel about the primary villain of the very first SW-movie? And lets be honest, Tarkin also had more screen-time than Dooku in one movie, than the later had in two.

There is so much potential there. Wilhuff Tarkin is member of an important clan in the Old Republic, he lived and spent his formative years during the ORs decline.
So how did his worldview develop, how did he become involved with Palpatine, how did this prodigy in xenobiology, engineering, philosophy and poetry turn first into the military and political mastermind, that not only formulated the Tarkin-doctrine, but formulated many other policies of the empire as well and in the end became the casual destroyer of Alderaan?
In many ways Tarkin is the intellectual founding-father of the empire or at least its military-technocratic aspects, the one person, who truly believed in the empire, while to the likes of Palpatine and Darth Vader it was never more than a tool for their own aggrandisement.

Even without involving the DeathStar, there is enough stuff to fill a huge novel in the way of Cloak of Deception. Family troubles and clan-rivalries on Eriadu, political intrigue and military action in the Outer Rim, scheming and manouvering in the Galactic Senate and at the Imperial Court. The decline and fall of the Old Republic and the rise and consolidation of imperial power.

And all of it without lightsabers or the force at the centre, but at best at the sides.

Tarkin is one of the big names of SW, directely from the movies and there is enough material in different sources that, if merged, could fill three books even without a talented writer filling out the remaining blanks. Without the DeathStar. Perhaps as lead-up to the DeathStar, but not as a focal point. His relationships with his cousin Ranulph, his brother Gideon and his son Garoche need exploration as well as his service in the Republic Outland Security Forces. His marriage to a member of the Motti-family. And so one and so on.

Please keep this thread about a possible Tarkin-novel. If you want novels about Daine Jir (=Danger???) or Dengar, create your own threats.

I had expected the Death Star novel to cover more in the way of the politics among the various major Imperial and corporate entities that had a stake in the game (e.g. Tarkin and the other moffs, Seinar's million and one companies, the Kuatis who didn't seem to want a hand in the DS project according to the Bounty Hunter Wars but made a big deal about it anyway, Tagge Company, etc), with Tarkin playing a central role in the middle of it all, unwittingly acting as Palpatine's #1 pawn setting up the other players while thinking he was doing it all himself.

Instead it came off more like Medstar. With Tarkin hanging with Motti at the gym lifting dumbells and talking about his GF.

So yeah. I'd be down with a better political intrigue novel centering on Tarkin.

He would need to have one big motivation for the novel to work, an overarching goal that defines his actions, because a mere collection of scenes from his life wouldn't be as interesting. Maybe the establishment of the Tarkin doctrine or the goal to become Emperor himself. Death Star was already done so it is not an option.
